In multiphase (=3) equilibrium calculations, when the Newton method is used to solve the material balance (Rachford-Rice) equations, poorly conditioned Jacobian can lead to false convergence. We present a robust successive substitution method that solves ... see more

Chemical transformations typically occur according to multiphase schemes. Changes in the concentrations of the starting materials and intermediates with time are not always described with increasing or decreasing functions. A detailed study of a complex p... see more

The double–tangent construction of coexisting phases is an elegant approach to visualize all the multiphase binary systems that satisfy the equality of chemical potentials and to select the stable state. In this paper, we show how to perform the double-ta... see more

. The purpose of this study is to analyze how the concept of markets equilibrium: the IS-LM Model. This research uses library research method by using reference sources from books and journals according to the theme. The author uses a qualitative method w... see more

This study aims to examine the effects of argumentation-supported problem-based learning (AS-PBL) carried out in the Chemistry-II laboratory course on the conceptual understanding of prospective science teachers about "Chemical equilibrium and Le-Chatelie... see more

This study aimed to determine the feasibility of e-worksheet assisted by liveworksheets to improve science process skills and collaboration on chemical equilibrium materials based on aspects of validity, practicality, and effectivity. This type of researc... see more

This study reports the development of the interactive electronic multimedia “Inquiry Play-Room” for use in rotation and equilibrium topics. This was designed following the steps of a guided inquiry laboratory model, containing video problems, feedback, vi... see more

Astaxanthin is a natural antioxidant, and the highest content of this compound is found in Haematococcus pluvialis microalgae. Microwave-assisted extraction (MAE) is one of the environmentally friendly extraction methods and has many advantages. This stud... see more

This paper presents a metaheuristic method, namely Equilibrium Optimizer (EO) to solve the economic dispatch (ED) problem. The main objective function to be achieved is to minimize the total fuel costs of all generating units to meet the total load demand... see more
